Speaking of Math

The graphing calculator has
taken over the science and math classrooms, but they generally leave out the
blind. Not anymore, with Texas Instruments’ Orion TI-84 Talking Graphing
Calculator. The system starts with an off-the-shelf TI-84 and has a snap on
Orion accessory that uses FonixTalk technology to provide haptic feedback when
keys are pressed and tell the student what it is doing. The calculator upgrade
costs $600 and can be connected to a Braille printer.
